Quite right, simply chucking away samples WILL introduce aliasing if the signal is not appropriately bandwidth limited first. In the case of a 96Khz signal resampled to 48kHz by throwing away alternate samples, all the original signal content between 24kHz-48kHz will be folded into the 0-24kHz region. -- Muggy ------------------------------------------------------------------------ Muggy's Profile: http://forums.slimdevices.com/member.php?userid=2258 View this thread: http://forums.slimdevices.com/showthread.php?t=32958 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
